What it means
Change automation evidence records what an automated change intended, who authorized it, what code and inputs ran, which targets changed, and whether outcomes matched the plan.
Why it matters
Automated change volume can exceed manual review capacity, making trustworthy machine-generated evidence essential for accountability and troubleshooting.
Practical focus
- Define the system boundary, accountable owner, approved purpose, material risks, and decision authority for Change Automation Evidence
- Bind requests, approvals, commits, pipeline runs, plans, identities, target inventories, execution results, validation, and rollback into one traceable record.
- Collect and protect this evidence: immutable logs, plan and apply output, artifact digests, target results, approvals, exceptions, reconciliation, and post-change health checks.
- Exercise this failure scenario as a planned test: a configuration change causes an outage, but teams cannot determine which pipeline run touched the affected systems or with which inputs.
Common mistakes
- Using the label Change Automation Evidence without defining the exact systems, data, people, decisions, and time period in scope
- Treating a policy statement or tool demonstration as proof that Change Automation Evidence operates consistently in production
- Failing to retain immutable logs, plan and apply output, artifact digests, target results, approvals, exceptions, reconciliation, and post-change health checks in a form that lets an independent reviewer reconstruct decisions and changes
- Testing only the normal path and never rehearsing what happens when a configuration change causes an outage, but teams cannot determine which pipeline run touched the affected systems or with which inputs.
